System and method to stimulate the optic nerve

Abstract

A method for application of light to one or more eyes ( 300 ) of a user is disclosed. The method comprises identification ( 110 ) of location of an optic disk ( 330 ) on a retina ( 320 ) in the one or more eyes ( 300 ) and selectively applying ( 115 ) the light onto the optic disc ( 330 ) to stimulate the optic disk ( 330 ).

What is claimed is: 
     
       1. A method for invisible targeting with light of melanopsin in one or more eyes of a user, comprising:
 identification of a location of an optic disk on a retina in the one or more eyes; and 
 positioning a light emitting source to spatially align a position and size of the light on the optic disk to make the emitted light invisible to the user; and 
 selectively applying the light, configured to stimulate melanopsin, onto the optic disc to invisibly target and stimulate the melanopsin located at the optic disk to inhibit a progression of myopia of the user. 
 
     
     
       2. The method of  claim 1 , wherein the light is selected to have wavelengths in a range of 360 to 540 nm. 
     
     
       3. The method of  claim 1 , wherein the identification comprises at least one of exposing the user to a stimulating light applied on the retina of the one or more eyes and monitoring perception of the stimulating light, or mapping of the retina. 
     
     
       4. The method of  claim 1 , wherein the light is emitted from one of an LED source, a laser emitter or a display device. 
     
     
       5. The method of  claim 1 , further comprising limiting a field of vision of at least one of the eyes. 
     
     
       6. The method of  claim 1 , further comprising monitoring at least one of a position of a pupil in the one or more eyes or a direction of sight of the one or more eyes. 
     
     
       7. The method of  claim 6 , further comprising changing composition of the light. 
     
     
       8. The method of  claim 1 , further comprising selectively applying the light onto other parts of the one or more eyes. 
     
     
       9. A method for a treatment of myopia of a user by invisible targeting with light of melanopsin in one or more eyes of the user, the method comprising:
 identification of location of an optic disk in a retina in one or more eyes; and 
 positioning a light emitting source to spatially align a position and size of the light on the optic disk to make the emitted light invisible to the user; and 
 selectively applying the light, configured to stimulate melanopsin, onto the optic disc to invisibly target and stimulate the melanopsin located at the optic disc to inhibit a progression of myopia of the user. 
 
     
     
       10. A device for invisible targeting with light of melanopsin in one or more eyes of a user, comprising:
 a controller for selecting light configured to stimulate melanopsin; 
 a light emitting source for emitting the light; 
 an identifier for identifying a location of an optic disk on a retina in the one or more eyes, and an optical system adapted to selectively apply the emitted light, configured to stimulate melanopsin, onto the optic disk, by positioning the light emitting source to spatially align a position and size of the light on the optic disk to make the emitted light invisible to the user and thereby stimulating the melanopsin located at the optic disk to inhibit a progression of myopia of the user. 
 
     
     
       11. The device of  claim 10 , further comprising a field of view limitation device. 
     
     
       12. The device of  claim 10 , wherein the controller is configured to select the light to have a wavelength in a range of 360 to 540 nm. 
     
     
       13. The device of  claim 10 , wherein the identifier comprises a device for mapping the retina of the one or more eyes. 
     
     
       14. The device of  claim 10 , wherein the light emitting source is one of an LED source, a laser emitter or a display device. 
     
     
       15. The device of  claim 10 , further comprising an eye tracking system or an electrography system for monitoring at least one of a position of a pupil in the one or more eyes or a direction of sight of the one or more eyes. 
     
     
       16. The device of  claim 15 , wherein the light emitting source is adapted to change composition of the light. 
     
     
       17. The device of  claim 10 , wherein the optical system further additionally applies the emitted light on to other parts of the one or more eyes. 
     
     
       18. The device of  claim 10 , further comprising one or more actuators for changing a position of the light emitting source. 
     
     
       19. The device of  claim 10 , wherein the optical system is adaptive to at least one of a position of a pupil in the one or more eyes or a direction of sight of one of the one or more eyes. 
     
     
       20. The method of  claim 1 , further comprising
 measuring at least one of external parameters and internal parameters, wherein the external parameters include an environmental light level, time-of-flight, and daytime, and wherein the internal parameters include physiological factors, heart rate, temperature, pupil size, eye lid position, age, size, and gender of the user; 
 wherein the selecting of the light configured to stimulate melanopsin is based on at least one of the measured parameters and predefined parameters.
